Use the dynamic worksheet to practice simplifying expressions with fractional exponents, rewriting them as radicals.

Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.

Exercises requiring expressions to be re-written in 'Simple Radical Form'.

Use two methods to find the sum of mixed numbers: improper fractions and mixed numbers

We can analyse the arrows in a food web to identify producers, primary consumers, secondary consumers, and decomposers.
